Review of the SIG SAUER MCX Gen II Pellet Air Rifle

Over the past year or so, I’ve been fortunate to try several airguns courtesy of the fine folks at Pyramyd AIR. The piece I’m about to review today is perhaps my favorite (so far). Maybe that’s because I’ve spent a fair amount of time shooting its traditional firearm cousin (the SIG MCX Virtus), or maybe it’s just that well-built. Honestly, it’s a combination of the two.

As you open the box, the front announces that the gun has “Authentic weight, balance, and handling.” That statement is spot-on.

When it comes to air rifles that blend power, precision, and realistic training capabilities, the SIG SAUER MCX Gen II pellet air rifle stands out as a top contender on anyone’s wish list. SIG’s second-generation air rifle aims to impress with its robust build, impressive accuracy, and user-friendly design.

Design and Build Quality

The SIG MCX Gen II mirrors the design of its firearm counterpart, the MCX Virtus, offering a realistic training experience without the noise and the need for expensive ammunition. Pyramyd offers a wide variety of pellets in .177 caliber that can be fired from the MCX.

The rifle features a sturdy polymer frame, which not only makes it durable but also relatively lightweight (7.35 lbs), ensuring ease of handling during extended shooting sessions. The sleek black finish gives it a professional and tactical look that appeals to casual enthusiasts and professionals alike.
